Title: Method foe improving dephosphorization efficiency of molten iron
Inventor: OOGAHIRA KAZUO
IPC: C21C1/02
Filed: 1980-10-27
Abstract: PURPOSE:To improve dephosphorization efficiency by increasing or decreasing an oxidizing agent according to the content of Si in molten iron and controlling the ratio of an Na2CO3-contg. flux and a gas for conveying in dephosphorizing P in the molten iron with Na2CO3. CONSTITUTION:According to the content of Si of molten iron 2 in a reaction vessel 1 of a ladle or the like, a 5-50kg oxidizing agent is beforehand added in terms of iron ore per ton of molten iron. The Si in the molten iron is oxidized and slagged off by this oxidizing agent to form slag 3, after which Na2CO3 is blown through a lance 5 into the molten iron 2 at 15-40 solid-air ratios with gaseous nitrogen 7 as a gas for conveying. Since the Si in the molten iron is beforehand removed, the rate of reaction of P with Na2CO3 is increased and the molten iron is dephosphorized at a high dephosphorization rate.

Title: Air suspension control device
Inventor: MISAWA MASAYA
IPC: B60G17/016
Filed: 1997-05-24
Abstract: PROBLEM TO BE SOLVED: To reduce costs by using the same type of air springs for driving wheels and driven wheels, and enable the load allotment to driving shaft and driven shaft to be changed when necessary, while the car height is maintained constant. SOLUTION: Air-control of air springs for driving shaft and driven shaft is performed by controlling separate solenoid valves 9A to 9D by means of a control unit 16. Car-height control is performed by air-controlling an air spring concerned so that the car-height detected by a car-height sensor 11 can reach a reference car-height. The movement of axle-load from the driving shaft to the driven shaft is done by first withdrawing air from the air spring for the driven shaft, and then supplying air to the air spring for the driving shaft. In order to equalize the axle-loads, the air springs are air-controlled so that the air pressure of the respective air springs, which are detected by a pressure sensor, become equal.

Abstract: PURPOSE:To enable obtaining COD(edge face destruction) free high output characteristics without the optical absorption at an edge face by positioning an optical guide layer at the same height with the active layer of a light emission unit at the edge face where the top of a mesa is made lower. CONSTITUTION:A groove is formed on an n-GaAs substrate 1 and then, a mesa stripe is formed to the direction perpendicular to the groove so a mesa 11 which is lower at near an end plane than the mesa at the center is formed. Then, semiconductor layers, an n-type Al0.41Ga0.59As clad layer 2, an Al0.08Ga0.92 As active layer 3, a p-type Al0.41Ga0.59As the first clad layer 4, a p-type Al0.30 Ga0.70As optical guide layer 5, a p-type Al0.41Ga0.59As the second clad layer 6 and an n-type GaAs electrode layer 7 are grown in sequence by using a vapor growth method such as MOCVD, etc. Since the height of the mesa 11 is lower at near the end plane, the optical guide layer 5 is positioned at the position of the active layer 3 of a light emission unit in comparison with the direction of the height. This enables obtaining a COD free high output characteristics without the optical absorption at the edge face.

Title: Semiconductor device and manufacture thereof
Inventor: MATSUOKA TAKASHI
IPC: H01L21/3205
Filed: 1988-06-17
Abstract: PURPOSE:To simplify a process for making micronization possible by forming the first wiring layer on a substrate or on the upper surface of a multilayer construction and directly forming a plate wiring layer on the wiring layer with no mediation of a power supply layer. CONSTITUTION:For instance, a substrate 1 made of a GaAs semiconductor, the first wiring layer 2 made of Au or the like formed on the substrate 1 and a plated wiring layer 5 formed by growth on the wiring 2 with no mediation of a power supply layer directly by an electrolytic plating method are formed. Since the plate wiring layer 5 is formed directly on the wiring layer 2 with no mediation of the power supply layer, a defect at the time of removing etching of the power supply layer is not to remain. Consequently, falling-off of the plated wiring layer 5 is hard to occur so that an operation also stabilizes. That is, reliability improves sharply, Further, in the process of the power supply layer, either a dry etching method or a wet etching method can be applied. Further, one time of a phototype process by a mask gats along. Still further, a construction finally leaving no power supply layer under the plated layer can be produced.

This powdered material is mixed with an adequate  amount of graphite powder and compacted. The green compact is heated and held at  1,100W1,200°C in an atmosphere of a decarburizing reducing gas. Thus, deoxidation,  alloying of carbon of the graphite powder and sintering are allowed to proceed, and  simultaneously decarburization is performed to form a hypoeutectoid region with alloyed carbon at the surface part and a hyper-eutectoid composition with alloyed carbon at the central part. The hot sintered body immediately after the sintering is oil- hardened and tempered at ≤250°C as required to manufacture the titled sintered  machine parts.

Abstract: PURPOSE:To secure alteration of the waveform of the rectangular wave voltage without varying the amplitude and period by installing the 2nd differential amplifier and then connecting the voltage variable circuit to the base of one of the transistors in the amplifier. CONSTITUTION:The 2nd differential amplifier 8 consisting of transistor Tr8a 8c is installed for the waveform control purpose, and the variable bias voltage is applied to the base of one of Tr8b in amplifier 8 from voltage variable circuit 9 comprising resistance 9a and variable resistance 9b. At the same time, the differetial output of the collectors in Tr8a and 8b is applied to the base of Tr3a in charge circuit 3 through Tr8a as well as to the base of Tr4a in discharge circuit 4 through Tr8b. In such constitution, resistance 9b is controlled to vary the base bias voltage of Tr8b, and thus the charge current of circuit 3 and the discharge current of circuit 4 are varied differentially. As a result, only the waveform can be controlled from the solid line, broken line and the 1-point chained line based on the scale of the bias voltage and in a simple way without varying the period of the rectangular wave voltage.

Title: Hydraulic valve
Inventor: YAMAYA TERUO
IPC: B60T11/34
Filed: 1995-05-25
Abstract: PURPOSE: To prevent foreign matters from ingressing in an air chamber, smoothly communicate the air chamber with outside air, and facilitate detection for lack of parts for sealing members after assembly by engaging the projections of a cover member with paired ring shaped grooves holding an opening, and forming a gap at a place interspaced with a main body member. CONSTITUTION: Paired ring shaped grooves 22a and 22b are formed in a main body 2 while holding an opening 20a at the outer circumference of a ventilating hole 20, and projections 21a and 21b provided for the inner circumference of a cover member 21 are engaged with the aforesaid grooves. By this constitution, water, dust and the like can be prevented from ingressing in an air chamber. Besides, since the opening 20a of the ventilating hole 20 is not completely blocked by the cover member 21 so as to allow a gap S to be formed therein, and thereby the air chamber is positively communicated with outside air, the pressure of the air chamber can be maintained at atmospheric pressure at all times, and thereby the movement of a stepped piston will never be obstructed by pressure in the air chamber.  And since leakage to the air chamber, which takes place when sealing members are short of parts, is transferred to the outside as is, lack of parts for the sealing members can thereby be easily detected.

Title: Liquid fuel combustor
Inventor: KITAJIMA SOUICHI
IPC: B05B17/06
Filed: 1977-12-15
Abstract: PURPOSE: To prevent the variation of atomization rate, i.e. combustion rate, that depends on the variation of liquid temperature, through the process consisting of detecting the temperature of liquid fuel and controlling the power supply rate of an ultrasonic oscillator.  
     CONSTITUTION: The temperature of the liquid fuel in an atomizing tank 7 is detected by a sensor 13, and the power supply rate of an ultrasonic oscillator 8 is changed accordingly. Namely, atomization rate is proportionate to the temperature of said liquid fuel. If this is left as it is, combustion rate also varies in accordance with liquid temperature. However, the variation of atomization rate that depends on the variation of liquid temperature can be prevented by increasing the power supply rate of said ultrasonic oscillator 8 when liquid temperature is high and increasing that when liquid temperature is low.
